[MDEP-728] Maven v4 / Plugin v4 Tidy Up parameters and messages

Description

The error message reads;

[ERROR] Failed to execute goal on project artifact-id: Could not resolve dependencies for project group-id:artifact-id:jar:VERSION: Cannot access central (https://repo.maven.apache.org/maven2) in offline mode and the artifact org.joda:joda-beans:jar:2.8.1 has not been downloaded from it before. -> [Help 1]

But you can't simply copy and paste that into get like this;

mvnw -N org.apache.maven.plugins:maven-dependency-plugin:3.1.2:get -Dartifact=org.joda:joda-beans:jar:2.8.1

It needs to be this;

mvnw -N org.apache.maven.plugins:maven-dependency-plugin:3.1.2:get -Dartifact=org.joda:joda-beans:2.8.1

The documentation for get requires this syntax;

groupId:artifactId:version[:packaging[:classifier]].

For Maven v4.x and/or maven-dependency-plugin v4.x could the error message match the input format, or the input format match the error message for easier copy/paste usage.

Personally I would prefer the error message to match the get artifact syntax as it makes more sense for me to be groupId:artifactId:version:packaging.
